A reamer is a type of rotary cutting tool used in metalworking. Precision reamers are designed to enlarge the size of a previously formed hole by a small amount but with a high degree of accuracy to leave smooth sides. There are also non-precision reamers which are used for more basic enlargement of holes or for removing burrs. The process of enlarging the hole is called reaming.
In the industrial and industry context, a reamer is a cutting tool used to enlarge, smooth, or shape a hole that has already been drilled or punched into a workpiece. Reamers are designed to remove small amounts of material from the inside surface of a hole with a high degree of accuracy and surface finish.
Examples of reamers in industrial and industry include:
- Hand reamers used for manual reaming operations in a variety of materials
- Machine reamers used for automated reaming operations in drilling machines and CNC machines
- Taper reamers used for reaming holes to a specific taper or angle
- Straight reamers used for reaming cylindrical holes
- Spiral reamers used for reaming holes with a helical flute pattern
- Chucking reamers used for reaming holes in small or thin parts
- Coolant-fed reamers used for reaming operations with coolant or lubricant for improved performance and tool life
- Adjustable reamers used for reaming holes to a specific size within a range of sizes.
